GEORGE T. BROWN, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO JAMESD. BROWN, OF SAME PLACE.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 682,134, datedSeptember 3, 1901. Application filed June '7, 1901. Serial No. 63,594.(No model.)

To all whom, it may concern: I Be itknown that I, GEORGE TUPPER BROWN,of Baltimore, in the State of Maryland, have invented certain new anduseful. Improvements in Lamp-B urners; and I hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, which form part of thisspecication. 'Y

This invention is an improvement in lampburners, and its object is toproduce a combined burner and collar by utilizing the collar both as asupport and casing for the wicktube and wick-raiser and also as thesupport for the globe or chimney.

A further object of the invention' is to enable the lamp-founts to beformed with a screw-threaded nipple and make the burner with anengaging-thread, so that the burner can be screwed directly onto thefount without having to provide the latter with a collar or nipple, ashas been heretofore necessary, thus simplifying and cheapening the c011-struction of parts and at the same time realizing material advantages,as will be hereinafter explained.

The invention briefly consists in the novel combined burner and collarhereinafter described and claimed, and illustrated in the accompanyingdrawings, in Which- Figure 1 is a side elevation of one of my improvedburners as applied to a fount and chimney, the construction illustratedin this ligure being particularly adapted for lanterns. Fig. 2 is avertical section through Fig. 1. Fig. 3 is a plan view of the burner,and Fig. 4 is a sectional view of a slight modification thereof.

The fount A of the lamp is provided with a screw-threaded nipple a,which is preferably formed integral with the fount by stamping, blowing,molding, &c., thereby doing away with the necessity for attaching acollar to the fount.

The burner consists of a threaded and inverted cap B, which is adaptedto screw onto and over nipple a, as shown. Through the top b of this cappasses the wick-tube C, which is supported thereby, and the wick-raiserD 5o is fastened onla rod E, which transxes the cap B, and is journaledin openings in opposite sides of the cap B just below top b.

It will be observed that the cap B and described connected parts formboth a complete burner and also a collar to protect the fount-nipplefrom injury. This device enables the brass collars ordinarily requiredand attached to the founts to be dispensed with, and as the nipple ismade with a thread it can be cheaply and readily formed integral 6o withthe fount in the process of making the latter. The metal collarsheretofore used increase the cost of manufacture and weaken the lamps,as their use necessarily makes two joints between burner and fount,whereas my improved burner and collar makes but one joint between burnerand fount.

The burner may be constructed to support a globe or chimney, and, asshown in Fig. 1, an annular plate Fis attached to the bottom 47o of capB, said plate being preferably perforated, as at f, and from theperiphery of plate F rises an annular ange G, which extends to or abovethe level ot' top l) and is preferably perforated, as shown at g. PlateF or flange G may be formed in any suitable Way or provided with anysuitable means to support a globe or chimney above and concentric to theburner, and, as shown in Fig. 1, part G is provided with a screw-threadG', which is en- 8o gaged by a corresponding thread I-I on the lower endof the lantern-globe H.

As shown in Fig. 4, the plate may be attached to the upper part of partB, as shown at F', and may be provided with lingers f or 85 any othersuitable chimney or globe retaining devices. In either case, however, itwill be observed that the cap B forms both the supportv for thewick-tube and wick-raiser and also the casing for the same, and also the9o collar for engaging or securing the burner on the nipple of thefount.

In the complete burner (shown in Figs. 1 and 2) it will be observed thatthe fount-engaging portion is actually within the body of the burner, sothat the latter might be termed a recessed burner, thereby bringing theburner nearer to the fount and making a very simple, strong, anddesirable construction for lamps, lanterns, &c. 1o@

Having thus described my invention, what I therefore claim as new, anddesire to secu re by Letters Patent thereon, is

l. In a burner, the combination of the threaded collar, the Wick-tubedepending therein, and the wick-raiser rod journaled in the collar; withthe chimney or globe supporting` devices exterior to and attached tosaid collar, substantially as described.

2. In a burner the combination of the threaded collar having a closedupper end, the Wick-tube depending through the top of said collar, theWick-raiser, and the supporting-rod thereof transxing said collar andjournaled in the opposite sides thereof; With the chimneyor globesupporting devices eX- terior to and attached to the collarsubstantially as described.

3. In aburner,'the combination of the fount having a threaded nipple,the burner having a threaded collar adapted to screw on the nipple, awick-guide suspended in said collar, a Wick-raiser, and awick-raiser-supporting rod journaled in the opposite Walls of thecollar; with the chimney or globe supporting devices exterior to butattached to the collar substantially as described.

4. The herein-described collar and burner, comprising aninternally-threaded collar, an annular plate surroundingand attached tosaid collar, and an annular iiange rising from said plate adapted tosupport a globeor chimney; a Wick-tube supported by and depending intothe collar, a wick-raiser rod extend ing through and journaled in saidcollar, and a wick-raiser on said rod also within the col= lar, allsubstantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
